经过两天的头部破坏后得到了答案。不敢相信。这是代码。只是为了输出FTSE 100的YQL查询数据。谢谢大家的回答！

<div id="finance"></div>

<script type="text/javascript" src="js/jquery-1.4.4.min.js"></script>
<script type="text/javascript">
$(function() {
    $.getJSON(

"http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22%5EFTSE%22)%0A%09%09&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=?", 

function(json){
  $('#finance').text(json.query.results.quote.Change);  
    // Patching payload into page element ID = "dog"
});


});
</script>

jQuery.getJSON()：使用 GET HTTP 请求从服务器加载 JSON 编码的数据。

jQuery.parseJSON：采用格式良好的 JSON 字符串并返回结果 JavaScript 对象。

你到底想输出什么？如果这是字符串格式的有效 JSON 对象，您可以使用...

var obj = eval(JSON);

JSON您从雅虎收到的提要在哪里。

然后，您可以访问对象的属性，例如。

var queryCount = obj.query.count;
